Quality Control

Our Propanoic Acid, 2,3-Diisocyanato-, Methyl Ester (9Ci) is produced and handled under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including assay, purity profiling, and identification, to ensure it meets precise specifications for research and industrial use. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and compliance with your project requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen) to prevent degradation. Recommended storage temperature is 2-8°C for long-term stability.
